[Q] How do you Undervolt?

---

So i have Daemon Controller 3.2 something and I've seen a lot of places mention undervolting. I looked around but couldn't find much information on it.. nothing extensive anyway. So my question is: what are the good things about undervolting (besides battery life) and what are the bad things?

If i undervolt and improve battery life does it decrease performance? Any info here would be awesome. Thanks!

The only thing I can think of that you might find as a benefit from U/V is improved battery life.

If you UnderVolt too far you risk freezing and/or damaging your device.

If you successfully undervolt without going too far and causing problems, you should see no negative effect on performance. Just better battery life.

I typically U/V around 50 for all clock ranges. I have never had any negative results doing this. But I haven't been able to prove I get better battery life either. I just take faith in the fact that I theoretically am. I do get wicked good battery life, but that is probably due to many things including kernel, rom, radio, clock speed settings, U/V settings, and other mods. All these together produce noticeable results, where any one by itself would not give any substantial or noticeable improvement.

Okay cool, I get pretty good battery life too so maybe I'll just skip UV.. no awesome reward just a lot of risk

There is a balance for reward vs risk there. Undervolting by 50 isn't going to put your phone in danger. But if it gets me a couple percent/an hour of battery life, why not?
I'm a believer in doing all the little things that add up to something substantial. Undervolt, Battery MOD, wifi policies, screen on time, charging habits, Kernel, ridding of problem apps, using things like Juice Defender, etc. These all add up to give me better battery life than you can find on almost any non-Max phone. But it takes all of them together, and a constant eye oout for something else I could be doing.

Undervolting may help you.

I havent been a big fan...on my og Incredible it caused nothing but problems with signal...so I dont anymore although the Sense kernel by Dres is undervolted a tad.

Give it a shot and start with -25 increments. Will it affect battery life? Maybe, but engineering tends to dictate that lower voltages dont always affect discharge rates. Higher voltages certainly affect consumption though (and can also lead to major problems).

I use the app SetCPU for CPU profiles. If I use something like Incredicontrol to undervolt, will it mess up my phone?

The only way to mess up your phone is to U/V too far and have the "Save for Boot" box checked and no NAND backup.

Make your NAND and run the U/V settings you choose for a day or two before you check the save for boot box. If it freezes up back off your settings a notch and run it for a couple more days.

I run about 50 under without any problems.
